DiabloSport Trinity How To: Upload a Custom Tune to Your Predator or Trinity User Manual
Page 3
‐If it says "Original Backup" bring the tool back to your car, and write any one of the
Performance tunes to the computer, this will make sure there is an Original Backup stored in
the tool, and will marry the tool to the vehicle's ECU (gifts will not be necessary).
2. Connect the tool to the computer, and power it up. If you do not have the DS Downloader
and correct driver program installed on your computer, follow the PREP instructions at the
bottom of the page.
3. Open the DS Down loader program and wait for it to connect to the tool. When it does, a
window will pop up on the DS Downloader that reads “A Diablosport tool was detected on
COM#” (you can hit the ‘close’ button on that window), and the screen of the tool will read
“The tool is now under remote control…”. NOTE: If the DS Downloader will not connect to the
tool, reference the Driver Troubleshooting at the end of these instructions.
4. If you do not have a copy of the vehicle’s Original Backup (the ORIGINAL STOCK TUNE) on
your computer’s hard drive, first make one (If you already have a copy of the Original Backup
upon your hard drive, proceed to step 5):
Go to the ‘Express Tune Mode’ tab on the DS Downloader, and select ‘Get Tune File From
Tool’. The Program will instruct you to ‘Select tune and click OK to continue’. Just highlight
‘Original Backup from Tool’ and click ‘OK’. A window will pop up with a status bar that reads,
‘Downloading Backup’, and when it’s finished it will give you a ‘Save File’ window to choose
where to save. Highlight the folder you want to save it in (Desktop is the easiest to retrieve, but
you can save it anywhere), and click ‘Save’.
5. Make sure that you download the custom tune as well (if it has been emailed to you), to the
Desktop or any folder that you can find it in. (It is best to download it by right‐clicking the link
and selecting “Save As”, so you can tell Windows where to save it).
6. Select ‘Send Tune File to Tool’, a window titled “Select PCM File for Download” will pop up
where you can browse for the Custom Tune, select ‘Open’. The DS Downloader program will
then ask you to select a matching Original Backup, just browse for and select the stock tune you
copied in step 4, and click ‘Open’.
7. The DS Downloader will then begin uploading the tune. When it is finished you can bring it to
the vehicle and install it.
